Answer:

X=140

Step-by-step explanation:

Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees

The attachment you are showing us shows that we already know two angles

(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360.

X+70+60+90=360

X=360-70-60-90

X=140

From the given number line, we have inequality as {x|x≤4.5}. Therefore, option B is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Inequalities on a number line allow us to visualize the values that are represented by an inequality. To represent inequalities on a number line we show the range of numbers by drawing a straight line and indicating the end points with either an open circle or a closed circle.

The amount of money Wally and Drake have left to save is equal to $29.96 if each one of them wanted to buy a telescope.

The amount of money left to be saved can be calculated by using an algebraic expression.

First, we determine the cost of two telescopes if each one of them wanted to buy a telescope to see the moons of Jupiter.

As the cost of one telescope is $62.48, the cost of two telescopes will be;

62.48 + 62.48 = 124.96

An algebraic expression can be given as;

95 + x = 124.96

where x is the money left to be saved.

Solving for x;

x = 124.96 - 95

x = 29.96

Hence, $29.96 is the amount left to be saved for each one of them to buy a microscope.

The composition of two functions f and g is denoted by f o g. It is defined as follows:

(f o g)(x) = f(g(x))

In other words, f o g is the function that results from applying f to the output of g.

In this case, we have:

(f o g)(x) = f(g(x)) = f(2/x+3) = 1/(2/x+3)-3 = (x-9)/(2x+9)

(g o f)(x) = g(f(x)) = g(1/x-3) = 2/(1/x-3)+3 = (2x-6)/(x-9)

\(\quad\)

Since our line is parallel to BC, slope of the line is,

\(\longrightarrow\rm{m_a=\dfrac{7-4}{2-(-10)}}\)

\(\longrightarrow\rm{m_a=\dfrac{1}{4}}\)

Since our line passes through A, the equation will be,

\(\longrightarrow\rm{y-y_A=m_a(x-x_A)}\)

\(\longrightarrow\rm{y-(-2)=\dfrac{1}{4}(x-5)}\)

\(\longrightarrow\rm{\underline{\underline{x-4y-13=0}}\quad\quad\dots(1)}\)

\(\quad\)

b. Finding equation of line passing through B and perpendicular to AC.

\(\quad\)

Since our line is perpendicular to AC, slope of the line is,

\(\longrightarrow\rm{m_b=-\dfrac{x_A-x_C}{y_A-y_C}}\)

\(\longrightarrow\rm{m_b=-\dfrac{5-(-10)}{-2-4}}\)

\(\longrightarrow\rm{m_b=\dfrac{5}{2}}\)

Since our line passes through B, the equation will be,

\(\longrightarrow\rm{y-y_B=m_b(x-x_B)}\)

\(\longrightarrow\rm{y-7=\dfrac{5}{2}(x-2)}\)

\(\longrightarrow\rm{\underline{\underline{5x-2y+4=0}}\quad\quad\dots(2)}\)

From (1),

\(\longrightarrow\rm{x=4y+13}\)

Putting this value of x in (2),

\(\longrightarrow\rm{5(4y+13)-2y+4=0}\)

\(\longrightarrow\rm{18y+69=0}\)

\(\longrightarrow\rm{y=-\dfrac{23}{6}}\)

Then,

\(\longrightarrow\rm{x=4\left(-\dfrac{23}{6}\right)+13}\)

Hence the intersection point is \(\bf{\left(-\dfrac{7}{3},\ -\dfrac{23}{6}\right)}.\)

To calculate \(\frac{{f(x+h) - f(x)}}{h}\) for the function \(f(x) = ax^3\), we need to substitute the expressions into the formula and simplify.

\(f(x+h) = a(x+h)^3\\\\f(x) = ax^3\)

Now we can calculate the difference:

\(f(x+h) - f(x) = a(x+h)^3 - ax^3\)

Expanding \((x+h)^3\):

\(f(x+h) - f(x) = a(x^3 + 3x^2h + 3xh^2 + h^3) - ax^3\)

Simplifying:

\(f(x+h) - f(x) = ax^3 + 3ax^2h + 3axh^2 + ah^3 - ax^3\)

The terms \(ax^3\) cancel out:

\(f(x+h) - f(x) = 3ax^2h + 3axh^2 + ah^3\)

Now we can divide by h:

\(\frac{{f(x+h) - f(x)}}{h} = \frac{{3ax^2h + 3axh^2 + ah^3}}{h}\)

Canceling out the common factor of h:

\(\frac{{f(x+h) - f(x)}}{h} = 3ax^2 + 3axh + ah^2\)

Now, we evaluate this expression again by setting h = 0:

\(\frac{{f(x+h) - f(x)}}{h} = 3ax^2 + 3ax(0) + a(0)^2\)

\(= 3ax^2\)

Therefore, when we evaluate the expression by setting h = 0, we get \(3ax^2\).

The probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 is approx b). 0.9428.

The intelligence quotient (IQ) test scores for adults are normally distributed with a population mean of 100 and a population standard deviation of 15. The standard deviation of the mean of a sample of 50 adults can be calculated as the population standard deviation divided by the square root of the sample size, or 15/√50 = 1.58.

Using a standard normal distribution table, the probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 can be calculated as the area under the standard normal curve between the z-scores corresponding to 98 and 103. These z-scores can be calculated using the formula z = (x - mean) / standard deviation, where x is the value of interest and mean is the population mean. The z-score for 98 is (98 - 100) / 1.58 = -1.27, and the z-score for 103 is (103 - 100) / 1.58 = 2.53.

The area under the standard normal curve between -1.27 and 2.53 can be found using a standard normal distribution table or a calculator with normal distribution functions. The probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 is approximately 0.9228, which is closest to the answer choice b. 0.9428.

The instantaneous acceleration at any time t is given by 10t. The limit definition of a derivative is true because it allows us to find the instantaneous rate of change of a function at a specific point.

To use the limit definition of a derivative to calculate instantaneous acceleration, we need to find the derivative of the velocity function with respect to time. The derivative of velocity gives us acceleration.

The limit definition of a derivative is given by:

f'(x) = lim (h→0) [f(x+h) - f(x)] / h

To calculate instantaneous acceleration, we substitute the velocity function, v(t), into the limit definition. Let's say v(t) = 5t^2.

Using the limit definition, we have:

a(t) = lim (h→0) [v(t+h) - v(t)] / h

Substituting v(t) = 5t^2, we get:

a(t) = lim (h→0) [5(t+h)^2 - 5t^2] / h

Expanding and simplifying:

a(t) = lim (h→0) [10th + 5h^2] / h

Now, we can cancel out the h term:

a(t) = lim (h→0) 10t + 5h

Taking the limit as h approaches 0, we get:

a(t) = 10t

Therefore, the instantaneous acceleration at any time t is given by 10t.

The limit definition of a derivative is true because it allows us to find the instantaneous rate of change of a function at a specific point. By taking the limit as the change in input approaches zero, we are able to approximate the exact rate of change at that point. This concept is fundamental to calculus and is used in various applications such as physics, engineering, and economics.

The given differential equation is y" - 4y' -21 = 0

This can be written as characteristic equation -

m² - 4m - 21 = 0

m² - 7m + 3m - 21 = 0

m(m - 7) + 3(m - 7) = 0

(m + 3)(m - 7) = 0

m = -3 and m = 7

The density of the liquid substance Y can be determined by using the conversion factor 1 atm = 41.5 ft⁻Y and the density of the liquid substance Y is approximately 19.68 ft⁻Y.

Conversion factor: 1 atm = 41.5 ft⁻Y

The "feet of liquid substance - Y" unit is defined as the pressure equivalent to the pressure that exists one foot below the surface of substance Y. In other words, if we go one foot below the surface of substance Y, the pressure will be equivalent to 1 ft⁻Y.

Since pressure is directly related to the density of a liquid, we can equate the pressure in units of atm to the pressure in units of ft⁻Y.

Therefore, we can say:

1 atm = 41.5 ft⁻Y

From this equation, we can conclude that the conversion factor for pressure between atm and ft⁻Y is 41.5.

we can calculate the conversion factor from "feet of liquid substance - Y" (ft⁻Y) to atm.

To convert from ft⁻Y to atm, we can use the inverse of the given conversion factor:

Conversion factor: 1 atm = 41.5 ft⁻Y

Taking the reciprocal of both sides:

1 / 1 atm = 1 / 41.5 ft⁻Y

Simplifying the equation:

1 atm⁻¹ = 0.024096 ft⁻Y⁻¹

Now, to find the density of the liquid substance Y in units of ft⁻Y, we can multiply the given density in g/cm³ by the conversion factor:

Density in ft⁻Y = 816.55 g/cm³ * 0.024096 ft⁻Y⁻¹
